关闭Win7的玻璃效果

关闭Win7的玻璃效果

DwmEnableComposition调用这个函数可关闭整个系统的玻璃效果

DwmSetWindowAttribute调用此函数可关闭某个窗口的玻璃效果

只适用xp以上系统，因为xp系统没有dwmapi.dll这个链接库

以下代码放在程序的BOOL CXXApp::InitInstance()中调用

关闭系统玻璃效果

typedef HRESULT (__stdcall *lpfnDwmIsCompositionEnabled)(BOOL *state);
typedef HRESULT (__stdcall *lpfnDwmEnableComposition)(UINT setstate);
lpfnDwmIsCompositionEnabled lpfnIsEnabled = 0;
lpfnDwmEnableComposition lpfnSetEnable = 0;

HMODULE library = ::LoadLibrary(_T("dwmapi.dll"));
bool result = 0;

if (0 != library)
{
lpfnIsEnabled =(lpfnDwmIsCompositionEnabled)GetProcAddress(library,"DwmIsCompositionEnabled");
lpfnSetEnable =(lpfnDwmEnableComposition)GetProcAddress(library,"DwmEnableComposition");

if (lpfnIsEnabled != 0)
{
BOOL enabled = FALSE;
result = SUCCEEDED(lpfnIsEnabled(&enabled)) && enabled;
}

if(result && lpfnSetEnable != 0)
{
result = SUCCEEDED(lpfnSetEnable(0/*Disable*/));
}

VERIFY(::FreeLibrary(library));
}

关闭某个窗口的玻璃效果
如果编译器是vs2008以上的版本的话，代码非常简单，只需要在窗口初始化的地方加下如下代码：

DWMNCRENDERINGPOLICY ncrp = DWMNCRP_DISABLED;
DwmSetWindowAttribute(GetSafeHwnd(),DWMWA_NCRENDERING_POLICY,&ncrp,sizeof(ncrp));

再包含下#include <dwmapi.h>

如果编译环境低于VS2008并且没有 VISTA SDK的话是如下的代码:

由于编译环境中没有dwmapi.h文件，所以需要的一些定义就得自己加了，如下加了两个枚举。

//关闭某个应用程序的玻璃效果，此代码须放在m_pMainWnd指针被赋值后调用以下代码
enum DWMWINDOWATTRIBUTE
{
DWMWA_NCRENDERING_ENABLED = 1, // [get] Is non-client rendering enabled/disabled
DWMWA_NCRENDERING_POLICY, // [set] Non-client rendering policy
DWMWA_TRANSITIONS_FORCEDISABLED, // [set] Potentially enable/forcibly disable transitions
DWMWA_ALLOW_NCPAINT, // [set] Allow contents rendered in the non-client area to be visible on the DWM-drawn frame.
DWMWA_CAPTION_BUTTON_BOUNDS, // [get] Bounds of the caption button area in window-relative space.
DWMWA_NONCLIENT_RTL_LAYOUT, // [set] Is non-client content RTL mirrored
DWMWA_FORCE_ICONIC_REPRESENTATION, // [set] Force this window to display iconic thumbnails.
DWMWA_FLIP3D_POLICY, // [set] Designates how Flip3D will treat the window.
DWMWA_EXTENDED_FRAME_BOUNDS, // [get] Gets the extended frame bounds rectangle in screen space
DWMWA_LAST
};
typedef enum _DWMNCRENDERINGPOLICY {
DWMNCRP_USEWINDOWSTYLE,
DWMNCRP_DISABLED,
DWMNCRP_ENABLED,
DWMNCRP_LAST
} DWMNCRENDERINGPOLICY;

然后在动态链接库中得到去掉玻璃效果的函数(DwmSetWindowAttribute)进而执行该函数
typedef HRESULT (WINAPI * TmpFun)(HWND,DWORD,LPCVOID,DWORD);
HMODULE library = ::LoadLibrary("dwmapi.dll");

TmpFun DwmSetWindowAttributeEX;
if (0 != library)
{
DwmSetWindowAttributeEX = (TmpFun)::GetProcAddress(library,
"DwmSetWindowAttribute");
if (DwmSetWindowAttributeEX)
{
DWMNCRENDERINGPOLICY ncrp = DWMNCRP_DISABLED;
(*DwmSetWindowAttributeEX)(m_pMainWnd->GetSafeHwnd(),DWMWA_NCRENDERING_POLICY,&ncrp,sizeof(ncrp));

}
VERIFY(::FreeLibrary(library));
}
